+This commit lets the user customize the address completion.\r
+\r
+The first change controls whether to build the address completion list\r
+based on messages you have sent or you have received (the latter is\r
+much faster).\r
+\r
+The second change add a possible filter query to limit the messages\r
+used -- for example, setting this to date:1y.. would limit the\r
+address completions to addresses used in the last year. This speeds up\r
+the address harvest and may also make the search less cluttered as old\r
+addresses may well no longer be valid.\r
+---\r
+\r
+I have fixed the bug pointed out by Michal in his review. It seems to\r
+work, but there are a lot of possible configurations,\r
+\r
+I also don't like my docstring for the notmuch-address-command\r
+defcustom, so any suggestions gratefully received.\r
+\r
+Also, I am not sure whether this is all to much complexity for this\r
+feature.\r
+\r
+Best wishes\r
+\r
+Mark\r
